The Thule fit kit is one component in a Thule roof rack system. When used with a foot pack, it allows you to mount a base rack for carrying luggage or sporting gear on your car roof. These kits are custom designed to clip around the door jamb without drilling, scratching, or damaging your car in any way. The fit kit requires a Thule Traverse foot pack and load bars to create a complete roof rack system. Each kit works only with specific vehicles - check the Thule Fit Guide to find the fit kit for your car. Backed by Thule's Lifetime Warranty. Manufacturer's part number: KIT1819
